Isn't it strange how names are decided?
Twenty-odd years ago, SIL was going to call her son Arthur (popular again now, of course, but back then, it was still very much an old man's name). Apparently, the midwife told her in no uncertain terms that she couldn't saddle a baby with a cat's name (remember the cat food advert?) and SIL chose another name.
Even my own name was down to the midwife who had just delivered me - when my mum said she was going to call me Rachel, the midwife said, "* is a much nicer name", and my mum went along with it. I only discovered this a few weeks ago, and thought it was a coincidence because Rachel was the name that DH and I would have used if we had had a daughter.
A friend of mine was meant to be called Carol, but when her father was sent to register the birth he forgot it, so plumped for the first name that came into his head - she ended up as Joan instead!
